Abstract

Cassava is a staple food after rice and maize in Indonesia. In general, parts of cassava plants that consumed are the leaves and tubers. This research aimed to compare antioxidant activity of leaves and tuber from six types of cassava (Manihot utilissima Pohl). The leaves and tubers of the cassava plant from Cibinong were extracted with methanol separately. Methanol extract was measured the inhibition percentage as an antioxidant using DPPH reagent at 100 ppm. Results showed that Pucuk Biru leaves type has the highest inhibition at 88.09% and IC50 of 45.161 ppm.Keywords: antioxidant, Cibinong, DPPH, IC50, Manihot utilissima Pohl ABSTRAKKetela pohon merupakan bahan pangan pokok setelah beras dan jagung di Indonesia. Bagian tanaman singkong yang umumnya dikonsumsi adalah daun dan umbi. Penelitian ini bertujuan untuk membandingkan aktivitas antioksidan daun dan umbi dari enam jenis singkong (Manihot utilissima Pohl). Daun dan umbi tanaman singkong dari Cibinong masing-masing diekstraksi secara terpisah menggunakan pelarut metanol. Ekstrak metanol yang diperoleh diukur persentase daya inhibisinya menggunakan metode peredaman radikal bebas dengan reagen DPPH pada konsentrasi 100 bpj. Hasil pengujian antioksidan menunjukkan bahwa bagian daun singkong jenis Pucuk Biru mempunyai daya inhibisi yang paling tinggi yaitu 88,09% dan IC50 sebesar 45,16 bpj.

Abstract

Malaria is still the leading cause of death worldwide with nearly half the worlds population at risk. Parasitic resistance to existing antimalarial drugs in the market makes the search for a source of new drugs from nature is very important. Therefore, the aims of this study are to determine in vitro antimalarial activity of endophytic fungi extract from turmeric root and to identify the selected isolate molecularly. Heme polymerization inhibition method was used as in vitro antimalarial assay. The selected isolate was thrn identified using ITS1, ITS2, and 5.8S sequences of rDNA. The result of this study obtained 16 isolates of endophytic fungi from root of turmeric plant with isolate code were of K.Cl.Sb.A1 - K.Cl.Sb.A16. All of the ethyl acetate extracts of isolated endophytic fungi have heme polymerization inhibition activity. K.Cl.Sb.A11 was the most active isolate on heme polymerization inhibition test with 94,31% at concentration of test material at 8 mg/mL and IC50 value at 1.84 mg/mL. Molecular analysis showed that K.Cl.Sb.A11 isolate was Penicillium sp. and potentially developed as an antimalarial drug.

Abstract

Antioxidant Activity of Endophytic Fungi Cb.Gm.B3 Extract from Cinnamon (Cinnamomum burmanni) TwigsABSTRACTThere are many degenerative diseases that are caused by a free radical effect. Cinnamon (Cinnamomum burmanni) contains cinnamaldehyde compounds that have activity as a powerful antioxidant and fight free radicals. Endophytic fungi can be found in cinnamon plants living symbiotically. Endophytic fungi produce a variety of bioactive metabolites including antioxidants. This research was conducted to isolate endophytic fungi from C. burmanni plant which is active as antioxidant. Endophytic fungi isolation was carried out using surface sterilization method and cultivated in PDA media. Antioxidant activity test was performed using free radical 2.2-diphenyl-1-picrylhydrazyl (DPPH) method. Selected isolates were then identified molecularly to determine their species. A total of nine fungi were isolated from cinnamon twigs. The result showed that the highest antioxidant activity was obtained from Cb.Gm.B3 with IC50 of 13.219 ± 0.755 µg/mL. The selected isolate Cb.Gm.B3 taxonomically has a high similarity with Neofusicoccum parvum isolate PEL23 (Accession no: KY053054.1).Keywords: antioxidant, Cinnamomum burmanni, 2.2-diphenyl-1-picrylhydrazyl, endophytic fungi, Neofusicoccum parvum ABSTRAKKayu manis (Cinnamomum burmanni) mengandung senyawa sinamaldehid yang memiliki aktivitas sebagai antioksidan kuat dan dapat menangkal radikal bebas. Dalam tanaman kayu manis terdapat kapang endofit yang hidup bersimbiosis. Kapang endofit dapat menghasilkan berbagai senyawa metabolit bioaktif termasuk antioksidan. Penelitian ini dilakukan untuk mengisolasi kapang endofit dari tanaman C. burmanni yang aktif sebagai antioksidan. Isolasi kapang endofit dilakukan menggunakan metode sterilisasi permukaan dan ditanam pada media PDA. Pengujian aktivitas antioksidan dilakukan menggunakan metode peredaman radikal bebas dengan reagen 2.2-difenil-1-pikrilhidrazil (DPPH). Isolat terpilih diidentifikasi secara molekuler untuk menentukan spesiesnya. Sebanyak 9 isolat kapang berhasil diisolasi dari jaringan ranting tanaman kayu manis. Aktivitas antioksidan tertinggi (IC50) didapatkan dari isolat Cb.Gm.B3 sebesar 13,219 ± 0,755 µg/mL. Isolat terpilih Cb.Gm.B3 secara taksonomi memiliki tingkat kemiripan yang tinggi dengan Neofusicoccum parvum isolat PEL23 (No. aksesi: KY053054.1).Kata Kunci: antioksidan, Cinnamomum burmanni, 2.2-difenil-1-pikrilhidrazil, kapang endofit, Neofusicoccum parvum
